Description:

Difference in color or shading of topcoat.


Cause:

Retouching after 15 minutes: Color float issues arise when a pigmented epoxy has been applied and is re-touched or rolled again after sitting for 15 minutes or longer. Different shades in the color may result.

Using different batch numbers: Coloring can vary from batch to batch. Different batches used on the same project can result in color variances.


Repair:

Back roll the entire area always using an 18”, woven, shed-resistant, 3/8” nap roller. Always try to go across the entire area from side-to-side.

When possible, recoats should always be completed with the same coating batch, if batches are different, blend colored (Part A) side first before adding Hardener.


Prevention:

If material needs to be re-touched or rolled for any reason, it needs to be done within 10 minutes of application.


Different batch numbers:

Always check to make sure that you have the same batch number on the pigmented side of the product prior to adding the hardener.
